The nurse administers the first dose of prazosin 1 mg PO to a client. Which nursing action is most appropriate following the administration of this medication?

A. Encourage oral fluids: While hydration is important, it is not the most immediate concern following the administration of prazosin. B. Record the client's weight: Weight monitoring is not specifically indicated after the initial dose of prazosin and is not a priority action in this context. C. Take a pulse oximetry reading: While monitoring oxygen saturation is important in many situations, it is not directly related to the administration of prazosin, which primarily affects blood pressure. D. Place the call bell in reach of the client: This is the most appropriate action. Prazosin can cause orthostatic hypotension, particularly after the first dose, leading to dizziness or fainting. Ensuring that the call bell is within reach allows the client to request help if they feel lightheaded or need assistance.
